Valve by Purpose

Valves for Blowers

VB Type Vacuum Relief Valve (Vacuum Breaker)

VB Type Vacuum Relief Valve (Vacuum Breaker)

Fluid Gas, Air
Pressure Range Over -9.8kPaG (For High Vacuum Use)
Material Body FC200, SCS13, SCS14, SCS16
Main Parts CAC406, SUS304, SUS316, SUS316L
Bore Diameter 25A - 300A
Note The valve protects containers, gauges, vacuum pumps, vacuum motors etc. from vacuum damage. The valve seat has a large diameter enough for mounting. Adjusting a lifting travel-length is easy.
When the valve is used outdoors, it uses the anti-rain cover. Material of the valve is changeable according to your requirements. By changing the part of inlet to a flange, another gas can be used. The valves are also used in nuclear power plants.

Note The valve is small and light. It operates securely at a low opening pressure such as 0.5Kg/cm2 or 0.05MPa. It doesn’t cause any extraordinary vibration or impact from opening to closing of the valve. The valve opens and closes the inlet according to variation of pressure. Set pressure is easily adjusted by the handle.

Set Pressure: 0.05MPa
Blow Down Pressure: 0.55MPa
Closing Pressure: 0.049MPa
Discharge Capacity (air) : 130Nm3/minute
